Application June 21, 1954, Serial No. 438,263

3 Claims. (Cl. 292-275) This invention relates to improvements in window devices and more particularly it is an object of this invention to provide a holding device for tilting windows which provides a greater selectivity of window positions than heretofore.

A further object of the invention is to provide a window holding device permitting variations in window positions all the way from completely open to completely closed.

Heretofore many devices have been provided for holding windows of the tilting type in various positions. One of the most common of these has been the use of a bar pivotally fixed to the window frame area at the top of the window, the bar having a plurality of notches for receiving the upper edge of the window sash itself,

whereby the wind-ow can be placed in one or more or the notches. This type of window holder has the disadvantage of only a small selectivity in window position. One

notch might be too far closed in proportion to the temnormally.

Attempts to eliminate the disadvantages of the notchbar have made it necessary to use a special sash and it is therefore an object of this invention to provide a holding device which is usable with the standard, most economical type of window sash.

Yet another object is to provide a holding device which canbe easily unhooked from a fitting which is permanently fixed to the sash, thus making it possible to remove the sash easily by this simple unhooking and without the necessity "of removing bolts or screws.

Other and further objects and advantages ofthe present invention will be apparent from the following detailed description, drawings and claims, the scope of the invention not being limited to the drawings themselves as the drawings are only for the purpose of illustrating away in which the principles of this invention can be applied. Other embodiments of the invention utilizing the same -or equivalent principles may be used and structural.-

"changes may be made as desired by those skilled in the art without departingfrom the present invention and the purview of the appended claims.

In the drawings:

assembly showing the window stop of myinvention secured thereon.

. Figure 2 is a cross-sectional view taken along the lines :2-2 of Figure 1.

Figure 3 is an enlarged detail of the window stop as seen when the Window is in the full open position, and

p Ice with dotted lines showing the position of the window stop if the window were in a nearly closed position.

Figure 4 is an exploded view showing the relative parts of the window stop of my invention.

The present invention is for use more particularly with the commonly referred to no-draft ventilating windows. This type of window is generally manufactured as a 'unit and has its greatest market in the farm building line. The frame 10 of this type of window assembly is inserted in an opening 12 provided in the side wall 14 of a building and is bolted, nailed or otherwise secured therein, as shown by the numeral 13 in Figure 2.

Extending inwardly from either side of and at right angles to the frame 10 are wings 16. The Wings 16 are two in number disposed vertically on either side of the frame and the rearward edges 22 thereof extend from a point adjacent the lower edge 20 of the frame upwardly and rearwardly.

As best seen in Figure 2 the upper edge of the wings 16 extends rearwardly in an arc to meet the rearward edge 22. This are follows the path of the upper'edge of the sash as it is adjusted in an open or closed position.

The window sash 24 has its lowermost horizontally disposed member either hinged or otherwise held in the frame. As illustrated in Figure 2 the lower end of sash is held in place by a cleat 28.

The window, as shown may be opened to various degrees of outward or inward placement and by pivoting at its lower edge will give indirect ventilation. The wings 16 play their part by funneling the air upward.

Many types of stops have been used to hold the window in different positions. cause rattling by the wind or can be jarred loose by the wind thereby damaging the sash in the resulting fall or shock.

The window stop of my invention provides a positive stop for such units and comprises the following:

A bracket 30 is secured to the upper horizontal member 35 of the window sash 24 by a screw 32 which extends through the aperture 31 provided in a downwardly extending portion of the bracket 30.

The upper end of the bracket 30 is bent at a right angle whereby it extends across the normally horizontal upper edge of the sash. This right angle portion of the bracket 30 causes no interference at times when the window is closed since there is clearance between the sash and the frame.

The right angle portion of the bracket 30 further insures stability for the single bracket fastening screw 32.

Thebracket 30 extends downwardly a short distance and the lower end turns upon itself forming an elongated aperture 34 therethrough. This may be best seen in Figures 3 and 4.

The aperture 34 provided in the downwardly extending portion of the bracket 30 is for the purpose of pivotally securing an elongated spacer member 36 thereto. The elongated spacer member 36 is preferably formed of wire bent into a U-shape having a closed rearward 'end 37 and forwardly extending side members 39. As best seen in Figure 4 the ends of the respective side members 39 are bent inwardly at right angles as shown at 38 and 40. The end portions 38 and 40, in assembly, protrude inwardly into the aperture 34 at their respective end thereof.

The closed portion of the elongated spacer member 36 extends rearwardly a substantial distance so that the side members 39 are slidably received in a clamping bracket generally indicated by the numeral 42.

Referring to Figure 4, the clamping bracket 42 compn'ses a base member 44 having-an aperture therethrough adjacent its rearward edge through which extends a bolt Most are not adequate in that they 48;' The bolt 48 extends upwardly through the base plate 44 and is secured thereto. by means of a nut 50. The

is threadedly received on the upwardly extending end of the bolt 48 which holds the clamping bracket 42 together.

The wing nut 64 further provides a means for locking the device. By unscrewing the wing nut 64 sufiicient tension of the clamping member 60 against the side members 39 of the elongated spacer member 36 is removed thereby permitting the member 36 to slide inwardly and outwardly of the clamping bracket 42.

The forward end of the base member 44 is provided with an aperture 70 for receiving an eye bolt 72. The eye bolt 72 holds the clamping bracket 42 to a horizontally disposed cross bar 74. The threaded end of the eye bolt 72 extends downwardly through an aperture 76 provided in the crossbar 74 and is secured therein by means of a washer 78 and a nut 80.

Apertures 82 are provided in the cross-bar 74 for receiving screws 84 which latter secure the respective end of the cross-bar 74 to the respective rearward edge of the wings 16 of the indirect ventilation unit.

As thus described, it will be seen that the inventor has fulfilled the intended objects in the provision of a window :stop for the tilt type indirect ventilation unit which is operated easily and allows the window to be set at any one of many open positions, varying all the way from completely open to completely closed. The selectivity is a very important feature in a stop of this type.

In use the window sash can be moved to any desired position by first loosening the wing nut 64, which allows the elongated spacer member 36 to be slidably adjusted inwardly or outwardly of the clamping bracket assembly 42. It will be seen that during adjustment the forward portion of the base member 44 is allowed to freely pivot on the eye-bolt 72. This may best be seen in Figure 4 of the drawings.

It will also be seen that in the event of a broken pane in the sash or the desire to paint the sash, it can be easily removed from the unit by springing the inwardly bent ends of the member 36 outwardly of the apertures 34 of the bracket 30 whereby the sash may be lifted free of the unit.

It will be seen that the device as shown in the drawing is old in many respects, many parts being similar to the conventional notched bar window device and assembly as described in Patent No. 1,899,943, titled Window Device and issued March 7, 1933 to J. B. Clay et al.

In this earlier patent a tilting window, window frame, fixed member opposite the window corresponding to the applicants bar 74, and elongated window spacing element corresponding to the applicants spacer member 36 are all old and so these broad terms for these members will be used in the following claims for simplicity. It will be seen that the wing nut 64, bolt 48 and clamping member 60 comprise a means for releasably attaching the window spacing element or spacer bar 36 to the cross-bar 74, which latter in a broad sense comprises a fixed member or element and could be of different construction and yet be usable with other parts of the invention.

The cross-bar 74 is preferably of resilient material so that the bar 74 can be used to exert pressure or tension against window and further against the frame through the spacing element or sliding bar 36.

The crossbar 74, having a resilient characteristic, can be forced into a position flexed outwardly away from said window by adjusting and setting the window spacing element 36 into a length substantially greater than the distance from the crossbar 74 to the sash 24 at a time when the sash 24 is in a closed position whereby the crossbar 74, being sprung outwardly, has a natural tendency to urge the spacing member 36 and the sash 24 toward the window frame 10. The resulting tight fit of the sash 24 in the frame It) prevents undue amounts of leakage of weather around the sash 24 and minimizes the danger to livestock and poultry by eliminating drafts.

It will be seen that the bracket 30 can also be referred to as a connection bracket 30 having a base portion 30' affixed to a suitable upper portion of the window sash 24 and having a pivotal connection portion 30", of substantially tubular shape, spaced inwardly from the outer side of a vertical part 30" of a base portion 30' of the connection bracket, and provided with an aperture 34, which preferably extends horizontally.

The elongated spacing member 36 can be thought of as having an outer end disposed at the connection bracket 30, the outer end of the spacing element 36 being interlocked with the connection bracket 30 by extending into the aperture 34. It will be seen that the inwardly turned portions 38 and 40 of the spacing element 36 are horizontally disposed and in that way the outer end of the spacing element 36 and the pivotal connection portion 30 of the connection bracket 30 are shaped for permitting the spacing element 36 to define swinging movements in a vertical plane about the connection bracket 30.

Although such vertical swinging movement can be accomplished with a connection of some other type, it is a part of the essence of my invention to have such a pivotal connection for vertical swinging movements.

From the foregoing description, it is thought to be obvious that a window stop constructed in accordance with my invention is particularly well adapted for use, by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as claimed.
